MAX5035BASA Equivalent & Substitute Parts

Part Overview

The MAX5035BASA is a buck switching regulator IC from Analog Devices Inc./Maxim Integrated, designed for step-down voltage conversion with a fixed 5V output at 1A output current. This device operates across a wide input voltage range of 7.5V to 76V and is housed in an 8-SOIC surface mount package. The MAX5035BASA is currently classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5035BASA is determined by strict equivalence across the following critical parameters:

• Output voltage specification (5V fixed)
• Output current capability (1A minimum)
• Input voltage operating range (7.5V to 76V)
• Switching frequency (125kHz)
• Package configuration (8-SOIC with 0.154" width, 3.90mm)
• Mounting technology (Surface Mount)
• Operating temperature range (-40°C to 125°C)
• Regulatory compliance (ROHS3, REACH Unaffected)

The MAX5035BASA+ qualifies as a direct substitute based on identical electrical specifications and package footprint. The primary distinction between these parts is product status and packaging format.

Engineering Selection Recommendations

The MAX5035BASA+ is the direct functional equivalent for applications currently using the MAX5035BASA. Both parts maintain identical electrical performance specifications and physical package dimensions, ensuring pin-for-pin compatibility and PCB footprint alignment.

Selection between these parts should be based on product availability and supply chain status. The MAX5035BASA+ carries active product status from the manufacturer, providing assured long-term availability and continued technical support. The MAX5035BASA, classified as obsolete, may face supply constraints and should be transitioned to the MAX5035BASA+ for new designs or production replenishment.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements, maintaining equivalent environmental and safety certifications. The tube packaging format of the MAX5035BASA+ is standard for active production components and presents no functional or performance differences compared to the original part.
